The invention relates to a system controlling or tracking the operation of household appliances or computer or entertainment equipment (subsequently appliance), comprising an accessory (1) which is attachable to an operating energy and/or water supply (4, 11) of the appliance. The accessory includes connections (3, 9) for sensors monitoring either a user's presence or activity status or an operating environment or wired connections (7, 12) for signals tracking a flow rate of water or energy consumption, and a processor or a control logic (15) for processing information received by way of said connections. The accessory monitors the operating status of an appliance connected therewith on the basis of energy claimed thereby (measurement 7) or a water flow rate (measurement 12) or temperature. In addition, the accessory monitors the signal of an accessory linked functionally with the operating environment of an appliance, such as the signal of a leak (18), smoke (17), carbon monoxide, gas or temperature sensor (23) or other operating status related signal or a user's activity status or presence. The accessory has control outputs for controlling (6, 13) the operation or operating energy or water of an appliance or the accessory transmits the control signals to local (5) or remote (3) communication. |
